Need help trying to find flight details from a flight. It didn’t record anything on DJI app and now the map says it’s been deleted on DroneDeploy. I am trying to find out the height as well as time and route.

If you kept them then try the exif data from the photos. I’m assuming you already tried to get the DroneDeploy logs from iTunes? if you email support you could probably get the flight logs that they capture, but that is different than what is stored on the iPad.
